When and why to use Drupal 9 multisite?
What is a Drupal multisite ?
“Drupal has a feature that allows separate, independent sites to be served from a single codebase. Each site has its own database, configuration, files, and base domain or URL."
Drupal is so powerful and modern that it allows you to run many websites on the same codebase. This is what multisite is all about. Just a few content management systems allow you to run multiple sites from one CMS.
